Google search upgrades make it harder for websites to win traffic

Type a query into the Google search bar on a smartphone and there’s a good chance the results will be dominated by .

That stems from a decision in 2015 to test a fourth ad, rather than three, at the top of search results. Some employees opposed the move at the time, saying it could reduce the quality of Google’s responses, according to people familiar with the deliberations. But the company brushed aside those concerns because it was under pressure to meet Wall Street growth expectations, one of the people said.

By 2016, the extra marketing slot was a regular feature. It’s one of the many ways the search leader has altered how it presents results since its early days. Another example is the pre-packaged information Google often displays in a box at the top of a page, rather than sending users to other websites.
